One of the two toilets here is not draining properly, even after applications of some pretty nasty chemical solutions. (Neat sulfuric acid, anyone?) Looks like we get to call the plumber again, only this time it will probably be at our cost. (The common drain for the kitchen plumbing clogged up last week. We're on the ground floor of a three-story building. The plumber determined that the blockage was in the common pipes. The condo association gets billed for that.) Still, I suppose if one is going to have plumbing issues, you could do worse than for them to happen at 10 AM on a weekday instead of at 11 PM on a Saturday, when they seem most likely to me.
